The largest is the whale shark, which has been known to get as large as 18 meters (60 feet). The smallest fits in your hand. And the great white shark is somewhere in the middle.

Leedsichthys problematicus, meaning "Alfred Leed's problem-causing fish", was another prehistoric ocean giant. Estimates put Leedsichthys at approximately 16.5m long, substantially larger than the average Megalodon.
The second biggest shark in the world is the basking shark
While they don't get quite as large as whale sharks, the largest one ever reliably measured was 12.27 metres or just over 40 feet long. This is enough to net them the title of the world's second-largest shark.
The Godzilla Shark is a unique and fascinating creature. At 6.7 feet long, this shark was one of the largest of its kind during its lifetime. By comparison, many modern sharks are much bigger. Yet this ancient shark was massive for its time.
The Hoffman's Dragon Shark (Dracopristis hoffmanorum) is an extinct species of shark that lived during the Carboniferous period about 307 million years ago. The fossil of this prehistoric shark was discovered in New Mexico in 2013, and the first full description was published in 2021.
In the original Japanese films, Godzilla and all the other monsters are referred to with gender-neutral pronouns equivalent to "it", while in the English dubbed versions, Godzilla is explicitly described as a male. In his book, Godzilla co-creator Tomoyuki Tanaka suggested that the monster was probably male.
Once he was a sub-adult, he even ate whales. After his Gyaos lunch he had a snickers for desert. Seriously though I'd guess Godzilla would eat other large irradiated creatures and plants like giant ants, mantises, fish, trees, or whatever. The short answer is: He eats whatever the hell he wants.
Megalodon is NOT alive today, it went extinct around 3.5 million years ago.
The smallest shark, a dwarf lantern shark (Etmopterus perryi) is smaller than a human hand. It's rarely seen and little is known about it, having only been observed a few times off the northern tip of South America at depths between 283–439 meters (928–1,440 feet).
Megalodon vs.
When it comes to size, the blue whale dwarfs even the largest megalodon estimates. It's believed blue whales can reach a maximum length of 110 feet (34 meters) and weigh up to 200 tons (400,000 pounds!).
The Blue Whale: Bigger Than Megalodon.
This data suggests that mature adult megalodons had a mean length of 10.2 metres (about 33.5 feet), the largest specimens measuring 17.9 metres (58.7 feet) long. Some scientists, however, contend that the largest forms may have measured up to 25 metres (82 feet) long.
A Livyatan would win a fight against a megalodon. The Livyatan has the size and speed advantage, bigger teeth, and it has endurance to last through a long fight. Another problem for the megalodon stems from the way that megalodons attack. They prefer to dig into the stomachs of their prey.
It's thought that megalodon sharks became extinct in part due to climate change: as oceans grew colder, they may not have been able to regulate their temperatures as needed. Lack of prey could be behind the megalodon's extinction, as many marine animals and fish could not survive the cold temperatures.
Hour after hour of small bite after small bite, the orcas would slowly whittle megalodon down. Still, if there were a single mistake, megalodon would easily dispatch the orca in a single bite, but another would always be there to take its place.
Megalodons are extinct. They died out about 3.5 million years ago. And scientists know this because, once again, they looked at the teeth. All sharks – including megalodons – produce and ultimately lose tens of thousands of teeth throughout their lives.
"Megalodon was not only a very big coastal shark that would definitely have been seen by now, it was also an apex predator higher on the food web than any living marine predator. As such, it would've been a huge influence on ocean ecosystems," he explained.
At a length of more than 50 feet (15 metres) and a mass of nearly 50 tons (tonnes), Megalodon was both larger and heavier than Tyrannosaurus rex.
What Did They Eat? A full-size Megalodon shark could extend to as much as 60 feet. Its humongous size allowed it to eat some of the largest mammals, such as dolphins, dugongs, sea lions, large fish, turtles, and even whales. However, not all Megalodon sharks could eat such big mammals.
Only a small number of plankton-eating sharks were equivalent or came close to its size. As for how the megalodons became so big, the researchers suggest a combination of live-birth and cannibalistic egg-eating among early-hatched embryos may have led to larger sizes inside their mother.
With its 300 sharp teeth, the great white has the most powerful bite in the animal world - 18,000 Newtons (1,835 kilograms force).
